Mix and flow of matter Flashcards
What are the 6 parts of particle theory of matter
1.all matter is made of particles
2.Particles are constantly in motion
3. Particles attract
4. particles always have space between them
5. as temperature increases particles move faster
6. atoms of the same elemant are iddentical and atoms of different elements are different
why cant solids flow
High intermolecular forces gives them a rigid shape
what is the oppisite of condensation
evaporation
What is the name of all the changes of state
Solid to liquid is melting
liquid to solid is freezing
Liquid to gas is vaporization
gas to liquid is condensation
Gas to solid is deposition
Solid to gas is sublimation
Whats the difference between pure substances and mixture
pure substance is made up of one component. Mixtures is made of atleast two different pure substances
what does unsaturated mixture mean
When the mixture doesnt have enough solute
what part of a solution gets dissolved, solvent or solute
The solute gets dissolved
What does heterogenous and homogenous mean
heterogenous is when components of a mixture is visible. While homogenous looks uniform.
According to the particle theory of matter, why does something dissolve?
The intermollecular forces of the solvent and solute over come forces of the solute
What title is given to water because of how many substances it can dissolve
“The Universal Solvent”
What means unablle to be dissolved in that solvent
Insoluble
What are three ways to increase speed of dissolving
Stirring, Heating, and smaller solute particles
Which dissolves faster, a sugar cube, or packet. Why?
Sugar packet because you expose more surface area
Viscosity of a high flow rate fluid
Low viscosity
When viscosity lowers, what happens to flow rate
High flow rate
